Liposuction - a lot of uneven skin and marks from cannula

Had lipo of abdomen and back in December 2021, immediately I noticed my back did not look different and I had a very large gap in my abdomen. At follow up the Dr. admitted that it was fat and needed a second procedure but I would have to pay for the fees of the surgery center. I waited a year to see if it would get any better, it did not. I chose to do it awake to see the doctor present etc.
The doctor was rude and for what ever reason they claimed I tested positive for a benzo. Which is 100% not true because I never take any pain meds. The whole time on the table he was bad mouthing me claiming I am taking benzo’s. Now 6 months post op I have a donut pocket of fat around my belly button along with a lot of uneven skin and marks from cannula. I reach out to the office every week asking for a refund or to speak to of their other surgeons but I so not get anywhere. The last email the office manager said that I signed something that says if I’m not happy I can not get a refund: this is not me being unhappy this is me being upset about having a bad doctor.
